Prevailing Wind Park is a 220 MW wind farm located in Yankton County, South Dakota. The facility began operating in 2020 and is owned and operated by AES Distributed Energy. The plant utilizes a single generator consisting of multiple onshore wind turbines. The turbines are manufactured by GE Wind, model GE3.8-137, with a hub height of 110 meters and a rotor diameter of 137 meters.
The plant's latest annual generation was 850,790 MWh, resulting in a capacity factor of 44.2%. Prevailing Wind Park is the fourth-largest wind farm in South Dakota out of 14, and ranks 219th nationally out of 734 wind plants. The facility operates within the Southwest Power Pool (SPP) balancing authority and the Midwest Reliability Organization (MRO) NERC region.

No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
